Armed Guard / CIT key terms

A limited power held by private persons to detain someone who has just committed a felony or certain offenses, typically requiring the person be handed to police without delay. Rules vary widely by state and must be verified locally.

Detention is a brief, temporary hold based on reasonable suspicion for investigation; arrest is a formal custody taking based on probable cause. Guards must know which action their legal authority actually permits.

A standard of belief that a specific person committed or is committing an offense, based on facts and circumstances rather than mere hunch. It is a higher threshold than reasonable suspicion and is required for arrest.

A lower standard allowing brief investigation when specific, articulable facts suggest criminal activity. It must be based on observable behavior, not stereotypes or intuition, and must be documented clearly.

Concrete, describable observations and details that support a decision to stop, detain, or escalate. If an officer cannot state the facts out loud, the action likely lacks legal support.

A graduated framework describing levels of resistance and matching reasonable responses, from presence and verbal direction up to deadly force. The response must always be proportionate and legally justified.

The legal test for force, judged from the perspective of a reasonable officer facing the same facts at the time, without hindsight. It weighs threat severity, immediacy, and the subject's actions.

Force intended or likely to cause death or serious bodily injury. It is permitted only when facing an imminent threat of death or serious injury, and it must be narrowly constrained by law and policy.

A danger that is immediate, present, and likely to cause harm within seconds. A past threat or a general risk is not imminent; the concept is central to justifying any defensive force.

A legal rule, applied in some jurisdictions, requiring a person to withdraw from a confrontation before using force if safely able. Many states limit or eliminate this duty in certain locations.

The lawful use of reasonable force to protect oneself from an imminent threat. It requires an honest and reasonable belief of danger and usually ends once the threat stops.

The practice of keeping the firearm's muzzle pointed in a safe direction at all times, regardless of whether the weapon is loaded. It is a primary rule that prevents unintentional injury.

Keeping the finger straight along the frame and off the trigger until the sights are on target and the decision to fire has been made. It reduces accidental discharge risk during handling.

A widely taught set of habits: treat every gun as loaded, never point at anything you do not intend to destroy, keep your finger off the trigger until ready, and know your target and what is beyond it.

The material or area behind a target that will stop a bullet. Before firing, the guard must confirm the backstop is adequate and that no bystanders are in the line of fire.

The area a guard can effectively and safely cover with the firearm from a given position. It must account for bystanders, cover, and the safe backstop before any shot is taken.

Cover is material that stops or slows bullets; concealment only hides a person from view. Guards must distinguish the two when choosing a defensive position during a threat.

Techniques and positioning that keep a firearm from being taken by someone else. It includes holster selection, body positioning, and defending the weapon during a close-quarters struggle.

A practiced sequence for clearing common firearm failures, such as a failure to feed or eject. Regular training builds the muscle memory needed to restore the weapon quickly under stress.

A standardized live-fire test that measures accuracy, speed, and safe handling to certify a guard's firearm proficiency. Passing is usually required at set intervals and documented.

The controlled sequence of drawing a firearm from a holster safely and consistently. It includes clearing the garment, obtaining a proper grip, and bringing the weapon up without sweeping the body.

A structured system assigning clear roles and a single person in charge during an emergency. It prevents conflicting orders and keeps communication and response coordinated.

A deliberate withdrawal from danger to a safer position while maintaining awareness and cover. It is often the best response and does not by itself constitute a failure of duty.

The actions taken during an ongoing attack, commonly summarized as run, hide, or fight. Guards should prioritize protecting lives, calling for help, and avoiding unnecessary confrontation.

Written instructions describing the duties, procedures, and expectations for a specific post. Guards must read and follow them, and they often govern escalation and reporting steps.

The practice of protecting items, scenes, and footage from contamination or loss until authorities take control. It includes limiting access, photographing, and notifying police.

A documented, unbroken record of who handled evidence, when, and for what purpose. Gaps or missing signatures can undermine the evidence in court or during an investigation.

A written account of an event that records who, what, when, where, and how, along with actions taken. It should be factual, objective, and free of opinion or speculation.

The skill of documenting observations and actions clearly, chronologically, and objectively. Good reports use plain language and specific details rather than conclusions or labels.

The process of confirming that a person is who they claim to be, using documents, biometrics, or records. It is a core step in preventing fraud and unauthorized access.

Examining an identity document for signs of forgery, tampering, or alteration. It includes checking physical features, security elements, and consistency of information.

A verification that a person is legally permitted to be employed in the relevant jurisdiction. It usually involves checking specific documents and keeping a record of the check.

Techniques that reduce tension and the likelihood of violence through calm communication, space, and active listening. The goal is to resolve conflict without force whenever possible.

Fully focusing on a speaker, reflecting back what was heard, and clarifying to show understanding. It builds rapport and helps calm a person during a tense interaction.

A communication approach that uses calm, respectful language to redirect hostility and gain voluntary cooperation. It emphasizes tone, empathy, and offering choices rather than commands.

A documented set of procedures for responding to fires, medical events, threats, and evacuations. It assigns roles and routes, and should be practiced through drills.

Sorting injured people by the urgency of their condition to direct limited resources where they are most needed. It is a core first-aid skill in a multi-casualty event.

Cardiopulmonary resuscitation and automated external defibrillator use for a person in cardiac arrest. Early compressions and timely defibrillation significantly improve survival chances.
